WhoisXML API’s Data Exchange Program for Internet Abuse Prevention

Internet abuse, particularly cybercrime, continues to grow in every corner of the domain name registration system. As cybercriminals increasingly weaponize domains, regardless of top-level domain (TLD), WhoisXML API launched the Data Exchange Program for Internet Abuse Prevention.


The program smooths out and expedites the collection and dissemination of critical domain, DNS, and IP intelligence between TLD registries, registrars, and other key Internet community members to reduce and prevent Internet abuse.


The Data Exchange Program for Internet Abuse Prevention is open to all ccTLD, gTLD, and new TLD registries and registrars worldwide.
